Abstract
[[abstract]]A numerical procedure for solving the electric field integral equation (EFIE) using the pulse-basis block model is proposed. The main features of the method are the use of face-centered node points and a unique way of choosing the unknown fields. Such a procedure keeps the resulting matrix relatively well conditioned even when the magnitude of the permittivity is large. In addition, the procedure can preserve the convolution property contained in the EFIE and, hence, the fast Fourier transform can be incorporated into the algorithm[[fileno]]2030130010030[[department]]電機工程學Keywords
